Chen v Cui

In the case of Chen v Cui, the dispute centred around a debt owed by the defendant to the plaintiff. The matter was heard in the Supreme Court of New South Wales, where the plaintiff sought to recover the outstanding debt. The plaintiff claimed that an oral agreement existed between the parties, which permitted the setting off of debts. The defendant, however, argued that no such agreement was made and that any set-off would not be applicable. The court was required to determine whether the magistrate had erred in not considering alternative claims to set off the debt that were not disclosed in the submissions. Specifically, the court had to consider whether an equitable set-off or a statutory right to set-off under the Civil Procedure Act 2005 (NSW) was available. Additionally, the court had to assess whether the money paid was at the request of the defendant, which would have implications for an equitable set-off and the doctrine of unjust enrichment.

The court found that the magistrate had failed to consider the possibility of an equitable set-off or a statutory right to set-off as provided for under the Civil Procedure Act 2005 (NSW), s 21(2). The court held that the magistrate's failure to consider these alternative claims was an error of law. The court further examined whether an oral agreement existed between the parties that allowed for the debts to be set off. The court concluded that while there was no written agreement, an oral agreement could be inferred from the conduct of the parties. Consequently, the court found that an equitable set-off was applicable in this case. Additionally, the court found that the money paid by the plaintiff was not at the request of the defendant, which meant that the doctrine of unjust enrichment did not apply.

The Supreme Court of New South Wales set aside the decision of the magistrate and remitted the matter back for reconsideration. The court directed the magistrate to consider the possibility of an equitable set-off under the circumstances of the case. The final orders of the court were that the matter should be remitted to the Local Court for the reconsideration of the claim, taking into account the findings of the Supreme Court.
